  39. MECHANSTIC ASPECTS OF BIOSYNTHESIS OF SILVER NANOPARTICLES

  40. MECHANSTIC ASPECTS OF BIOSYNTHESIS OF SILVER NANOPARTICLES Naik et al. Nature Mater. 2002, 1, 169-172. Ohio, USA The silver-binding peptides from Pseudomonas stutzeriAG259 cells were obtained by using a combinatorial approach to identify these peptides from a phage display library of random peptides. The interaction of peptide with the metal clusters provides a chemically reducing environment around the cluster, thereby allowing further accelerated reduction of silver ions at the interface between peptide and metal.
